Good evening fellow CA users.   Got a nice gig for a Florida house that required rafter tails.  That part was easy, but wondering how to put the painted board on the underside?  I added thickness via Roof Surface Definition but it creates under whole roof plane.  Just watched a couple training vids. too, and nothing noting this part.  I checked and unchecked a lot of buttons too on the roof dbx.. so I am thinking its a combination?
